It features a 0.5 inch diameter with a 0.2500 inch nose radius, a 1.25 inch length of cut, and a 36-degree right-hand spiral helix. The 3-flute geometry promotes efficient chip evacuation and smooth surface finishes. With a 6 inch overall length and a 0.5 inch shank diameter held to h6 tolerance, this tool fits standard collet chucks and end mill holders used in CNC machining centers and manual mills. It is a single-end, uncoated tool from M.A. FORD Series 138B.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling aluminum, copper, brass, and other non-ferrous materials in job shop, production, and tool-and-die environments. The 36-degree helix angle reduces cutting forces and promotes clean entry on contoured and 3D profiling passes. The regular-length designation makes it a practical choice for general-purpose slotting, profiling, and finishing operations where extended reach is not required. Machinists and CNC programmers running non-ferrous materials will find the uncoated carbide substrate appropriate for high-speed applications where coatings could introduce edge buildup concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 inch mill diameter with +0.000 to -0.005 inch tolerance for close-tolerance work\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral design optimized for non-ferrous metal stock removal and finishing\u003c\/li\u003e\n\u003cli\u003e36-degree helix angle reduces cutting forces and improves surface finish on contoured passes\u003c\/li\u003e\n\u003cli\u003e0.2500 inch nose radius for smooth ball-end profiling and 3D contouring\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 0.5 inch h6-tolerance shank for secure toolholder engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 0.5 inch collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual knee mills.

Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before loading or removing the tool. Verify runout with a dial indicator after clamping, as excessive runout accelerates flute wear and reduces dimensional accuracy. Follow the toolholder manufacturer torque guidelines when tightening collet nuts or set screws.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 138B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 138B50002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51740425355570,"sku":"138B50002","price":287.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e41b95de92f4f400bd8f8c63cdf1ad4d_8de632ff-0e4c-4f04-ad47-1e1b9b005445.jpg?v=1788824932","url":"https:\/\/voomisupply.com\/products\/m-a-ford-138b50002-ball-end-mill-0-5-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
